Utilisation de DeleteCluster avec un kit AWS SDK ou une interface de ligne de commande

Suppression d’un cluster sans instantané de cluster final Cet exemple supprime un cluster, forçant ainsi la suppression des données afin qu’aucun instantané de cluster final ne soit créé. Commande :

aws redshift delete-cluster --cluster-identifier mycluster --skip-final-cluster-snapshot

Suppression d’un cluster, autorisant ainsi un instantané de cluster final Cet exemple supprime un cluster, mais spécifie un instantané de cluster final. Commande :

aws redshift delete-cluster --cluster-identifier mycluster --final-cluster-snapshot-identifier myfinalsnapshot
